These floating habitats play a vital role in marine ecosystems by providing food, shelter, and breeding grounds for a wide variety of sea life, including fish, sea turtles, crabs, shrimp, and seabirds.

Our artificial Sargassum is carefully designed to replicate the natural look and function of real brown algae, making it perfect for use in aquariums, exhibitions, or creative underwater installations, whether for aesthetic or practical purposes.

Please note: The numbers shown under “Size” (8, 12, 16, or 24) refer to the total number of individual fronds combined to create one complete piece of artificial Sargassum.

This is not the quantity of separate units you will receive, but the amount of fronds used to build the overall size and fullness of one Sargassum piece.

The higher the number, the larger and denser the final product will be.

Distribution: Macrocystis pyrifera is common along the coast of the eastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, Australia, and New Zealand.

Description: Macrocystis pyrifera, commonly known as giant kelp or giant bladder kelp is the largest of all algae. The stage of the life cycle that is usually seen is the sporophyte, which is perennial and individuals persist for many years. Individuals may grow in excess of 50m (160ft) long. The kelp often grows even longer than the distance from the bottom to the surface as it will grow in a diagonal direction due to the ocean current pushing against the kelp. The stalks arise from a holdfast and branch three or four times from near the base. Blades develop at irregular intervals along the stipe, with a single pneumatocyst (gas bladder) at the base of each blade.

*Price includes terminal blade and stem for anchoring (rock bases sold seperately)

Scientific Name: Vallisneria Gigantea

Number of Blades/Leaves: 6

Mount: Available On Disk or on Suction Cup

Blade/Leaf Width: 16mm

Distribution: Vallisneria sp. is widely distributed in tropical and subtropical regions of Asia, Africa, Europe, and North America.

Description: Vallisneria sp. is a genus of freshwater aquatic plant, commonly called eelgrass, tape grass or vallis. It is a submerged plant that spreads by runners and sometimes forms tall underwater meadows. Leaves arise in clusters from their roots. The leaves have rounded tips, and definite raised veins. This plant should not be confused with Zostera species, marine seagrasses that are usually also given the common name “eelgrass.”

Number of Blades/Leaves: Available in 10 blades/piece

Blade/Leaf Width: 10mm

Distribution: Thalassia testudinum is found growing in meadows in calm shallow waters throughout the Caribbean Sea and the Gulf of Mexico and as far north as Cape Canaveral in Florida.

Description: Thalassia testudinum, or turtlegrass is a perennial grass growing from a long, jointed rhizome that may be buried 25 centimeters (9.8in) deep in the substrate but is more usually found 5 to 10cm (2 to 4in) below the surface. Some nodes are leafless but others bear a tuft of several erect, linear leaf blades. These are up to 30 centimeters (12in) long and 2cm (0.8in) wide and have rounded tips. The flowers grow on short stalks in the axils of the leaves and are greenish-white, sometimes tinged pink, and are followed by seed pods.

Number of Blades/Leaves: 6

Blade/Leaf Width: 24mm

Distribution: Fucus serratus is found along the Atlantic coast of Europe from Svalbard to Portugal, in the Canary Islands and on the shores of north-east America.

Description: Fucus serratus is a seaweed also known as toothed wrack or serrated wrack. F. serratus is a robust algae, olive-brown in color and grows from a discoid holdfast up to 180 centimeters (6ft) long. The fronds are flat, about 2cm (0.8in) wide, bifurcating, and up to 1m (3ft 3in) long including a short stipe. It branches irregularly and dichotomously. The flattened blade has a distinct midrib and is readily distinguished from related taxa by the serrated edge of the fronds.

Scientific Name: Phyllospadix scouleri

Number of Blades/Leaves: 20

Blade/Leaf Width: 2mm-3mm

Distribution: Phyllospadix scouleri is native to the coastline of western North America from the Alaskan panhandle to Baja California.

Description: Phyllospadix scouleri, or Scouler’s surfgrass, is a flowering marine plant in the family Zosteraceae. This slender, vivid green plant has long, flat blades. It grows in large clumps or beds exposed during low tide and submerged at high tide. It is found attached to rocks in middle to low intertidal zones to a depth of about 40–50ft.

Number of Blades/Leaves: 10

Blade/Leaf Width: .5mm

Distribution: Chaetomorpha linum is an intertidal and supralittoral species that can be found in groups of hundreds or thousands of individuals in sandy areas, on rocks or around tide pools. It is found around the British Isles and around Europe into the Mediterranean. In North America it is to be found along the Atlantic coast and in California.

Description: Chaetomorpha linum is a delicate green seaweed. Also known as spaghetti algae, it grows as a filamentous loosely entangled mass. Usually free-floating, it may also be attached to rocks and shells. The filaments themselves are unbranched and usually between 5 and 30cm in length. The unattached filaments are wiry, stiff and curled in appearance. It is bright light to dark green in color.

Scientific Name: Cymodocea nodosa

Number of Blades/Leaves: 68

Blade/Leaf Width: 35cm

Mount: On Rhizome

Distribution: Cymodocea nodosa is found in shallow parts of the Mediterranean Sea and the adjoining parts of the Atlantic Ocean, the coasts of Portugal, Mauritania and Senegal and round the Canary Islands, Madeira and the island of Cape Verde.

Description: Cymodocea nodosa is a species of seagrass in the family Cymodoceaceae and is sometimes known as little Neptune grass. C. nodosa has light green or greyish-green leaves. They are very narrow but may be up to 40cm long. Each leaf has seven to nine veins running along its length. The plant produces rhizomes which are only 1mm in diameter and have leaf scars at intervals. Inconspicuous grass-like flowers are sometimes produced at the end of long stems in the spring when water temperatures begin to rise after their winter minimum. The pollen is liberated into the sea and the seeds remain dormant until the following spring.

Distribution: Postelsia palmaeformis is found along the western coast of North America, from as far north as Vancouver Island, to the southern central coast of California. it inhabits rocky shores with constant waves. It is one of the few algae species that can survive and remain erect out of the water; in fact, it spends most of its life cycle exposed to the air.

Description: Postelsia palmaeformis, also known by the common name Sea Palm is an intertidal brown algae that occurs on rocky shores of the Pacific coast of North America, usually in patches from a few to hundreds of individuals. As an autotroph, it produces its own food via photosynthesis. Postelsia palmaeformis is an annual and like many brown algae has two distinct morphologies during its lifecycle – the microscopic gametophyte and the macroscopic sporophyte, which resembles a small palm tree. The sporophyte’s maximum height is variable, but can reach 60-75cm. This item measures approx 35.43″ (90cm) tall!

Number of Blades/Leaves: 1

Blade/Leaf Width: Available in Small, medium, and Large

Distribution: The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world’s oceans.

Description: Sea lettuce is a bright green algae composed of lobed, ruffle-edged leaves that are coarse and sheet-like and resemble a leaf of lettuce. The leaves may appear flat, thin, broad, and often rounded or oval. Its leaves are often perforated with holes of various sizes. Almost no stalk exists at the point of attachment, and no true roots are present.
